Chemist, Donald Hornig, owned this house in 1967. He worked on development of the atomic bomb at the Los Alamos National Laboratory. Hornig, then 25 years old, guarded the final atomic test bomb hours before it was detonated. The next morning he flipped the switch detonating the coffee can sized bomb. That successful test led to the production of "Little Boy," the atomic bomb that would end World War II and change the course of history. Hornig became a member of the faculty at Brown University in 1946 and Princeton University in 1957. He was a science advisor to presidents John F. Kennedy and Lyndon B. Johnson. Hornig returned to Brown University in 1970 and was president until 1976. He then became associated with Harvard University where he retired from in 1990.
